+# Setup
+
+This guide walks through how to run the repository locally and check in your first code.
+For a [development container](https://containers.dev/), see the [.devcontainer folder](https://github.com/langchain-ai/langchain/tree/master/.devcontainer).
+
+## Dependency Management: Poetry and other env/dependency managers
+
+This project utilizes [Poetry](https://python-poetry.org/) v1.7.1+ as a dependency manager.
+
+❗Note: *Before installing Poetry*, if you use `Conda`, create and activate a new Conda env (e.g. `conda create -n langchain python=3.9`)
+
+Install Poetry: **[documentation on how to install it](https://python-poetry.org/docs/#installation)**.
+
+❗Note: If you use `Conda` or `Pyenv` as your environment/package manager, after installing Poetry,
+tell Poetry to use the virtualenv python environment (`poetry config virtualenvs.prefer-active-python true`)
+
+## Different packages
+
+This repository contains multiple packages:
+- `langchain-core`: Base interfaces for key abstractions as well as logic for combining them in chains (LangChain Expression Language).
+- `langchain-community`: Third-party integrations of various components.
+- `langchain`: Chains, agents, and retrieval logic that makes up the cognitive architecture of your applications.
+- `langchain-experimental`: Components and chains that are experimental, either in the sense that the techniques are novel and still being tested, or they require giving the LLM more access than would be possible in most production systems.
+- Partner integrations: Partner packages in `libs/partners` that are independently version controlled.
+
+Each of these has its own development environment. Docs are run from the top-level makefile, but development
+is split across separate test & release flows.
+
+For this quickstart, start with langchain-community:
+
+```bash
+cd libs/community
+```
+
+## Local Development Dependencies
+
+Install langchain-community development requirements (for running langchain, running examples, linting, formatting, tests, and coverage):
+
+```bash
+poetry install --with lint,typing,test,test_integration
+```
+
+Then verify dependency installation:
+
+```bash
+make test
+```
+
+If during installation you receive a `WheelFileValidationError` for `debugpy`, please make sure you are running
+Poetry v1.6.1+. This bug was present in older versions of Poetry (e.g. 1.4.1) and has been resolved in newer releases.
+If you are still seeing this bug on v1.6.1+, you may also try disabling "modern installation"
+(`poetry config installer.modern-installation false`) and re-installing requirements.
+See [this `debugpy` issue](https://github.com/microsoft/debugpy/issues/1246) for more details.
+
+## Testing
+
+**Note:** In `langchain`, `langchain-community`, and `langchain-experimental`, some test dependencies are optional. See the following section about optional dependencies.
+
+Unit tests cover modular logic that does not require calls to outside APIs.
+If you add new logic, please add a unit test.
+
+To run unit tests:
+
+```bash
+make test
+```
+
+To run unit tests in Docker:
+
+```bash
+make docker_tests
+```
+
+There are also [integration tests and code-coverage](/docs/contributing/testing/) available.
+
+### Only develop langchain_core or langchain_experimental
+
+If you are only developing `langchain_core` or `langchain_experimental`, you can simply install the dependencies for the respective projects and run tests:
+
+```bash
+cd libs/core
+poetry install --with test
+make test
+```
+
+Or:
+
+```bash
+cd libs/experimental
+poetry install --with test
+make test
+```
+
+## Formatting and Linting
+
+Run these locally before submitting a PR; the CI system will check also.
+
+### Code Formatting
+
+Formatting for this project is done via [ruff](https://docs.astral.sh/ruff/rules/).
+
+To run formatting for docs, cookbook and templates:
+
+```bash
+make format
+```
+
+To run formatting for a library, run the same command from the relevant library directory:
+
+```bash
+cd libs/{LIBRARY}
+make format
+```
+
+Additionally, you can run the formatter only on the files that have been modified in your current branch as compared to the master branch using the format_diff command:
+
+```bash
+make format_diff
+```
+
+This is especially useful when you have made changes to a subset of the project and want to ensure your changes are properly formatted without affecting the rest of the codebase.
+
+#### Linting
+
+Linting for this project is done via a combination of [ruff](https://docs.astral.sh/ruff/rules/) and [mypy](http://mypy-lang.org/).
+
+To run linting for docs, cookbook and templates:
+
+```bash
+make lint
+```
+
+To run linting for a library, run the same command from the relevant library directory:
+
+```bash
+cd libs/{LIBRARY}
+make lint
+```
+
+In addition, you can run the linter only on the files that have been modified in your current branch as compared to the master branch using the lint_diff command:
+
+```bash
+make lint_diff
+```
+
+This can be very helpful when you've made changes to only certain parts of the project and want to ensure your changes meet the linting standards without having to check the entire codebase.
+
+We recognize linting can be annoying - if you do not want to do it, please contact a project maintainer, and they can help you with it. We do not want this to be a blocker for good code getting contributed.
+
+### Spellcheck
+
+Spellchecking for this project is done via [codespell](https://github.com/codespell-project/codespell).
+Note that `codespell` finds common typos, so it could have false-positive (correctly spelled but rarely used) and false-negatives (not finding misspelled) words.
+
+To check spelling for this project:
+
+```bash
+make spell_check
+```
+
+To fix spelling in place:
+
+```bash
+make spell_fix
+```
+
+If codespell is incorrectly flagging a word, you can skip spellcheck for that word by adding it to the codespell config in the `pyproject.toml` file.
+
+```python
+[tool.codespell]
+...
+# Add here:
+ignore-words-list = 'momento,collison,ned,foor,reworkd,parth,whats,aapply,mysogyny,unsecure'
+```
+
+## Working with Optional Dependencies
+
+`langchain`, `langchain-community`, and `langchain-experimental` rely on optional dependencies to keep these packages lightweight.
+
+`langchain-core` and partner packages **do not use** optional dependencies in this way.
+
+You'll notice that `pyproject.toml` and `poetry.lock` are **not** touched when you add optional dependencies below.
+
+If you're adding a new dependency to Langchain, assume that it will be an optional dependency, and
+that most users won't have it installed.
+
+Users who do not have the dependency installed should be able to **import** your code without
+any side effects (no warnings, no errors, no exceptions).
+
+To introduce the dependency to a library, please do the following:
+
+1. Open extended_testing_deps.txt and add the dependency
+2. Add a unit test that the very least attempts to import the new code. Ideally, the unit
+test makes use of lightweight fixtures to test the logic of the code.
+3. Please use the `@pytest.mark.requires(package_name)` decorator for any unit tests that require the dependency.
+
+## Adding a Jupyter Notebook
+
+If you are adding a Jupyter Notebook example, you'll want to install the optional `dev` dependencies.
+
+To install dev dependencies:
+
+```bash
+poetry install --with dev
+```
+
+Launch a notebook:
+
+```bash
+poetry run jupyter notebook
+```
+
+When you run `poetry install`, the `langchain` package is installed as editable in the virtualenv, so your new logic can be imported into the notebook.

+
+# Setup
+
+LangChain documentation consists of two components:
+
+1. Main Documentation: Hosted at [python.langchain.com](https://python.langchain.com/),
+this comprehensive resource serves as the primary user-facing documentation.
+It covers a wide array of topics, including tutorials, use cases, integrations,
+and more, offering extensive guidance on building with LangChain.
+The content for this documentation lives in the `/docs` directory of the monorepo.
+2. In-code Documentation: This is documentation of the codebase itself, which is also
+used to generate the externally facing [API Reference](https://python.langchain.com/v0.2/api_reference/langchain/index.html).
+The content for the API reference is autogenerated by scanning the docstrings in the codebase. For this reason we ask that
+developers document their code well.
+
+The `API Reference` is largely autogenerated by [sphinx](https://www.sphinx-doc.org/en/master/)
+from the code and is hosted by [Read the Docs](https://readthedocs.org/).
+
+We appreciate all contributions to the documentation, whether it be fixing a typo,
+adding a new tutorial or example and whether it be in the main documentation or the API Reference.
+
+Similar to linting, we recognize documentation can be annoying. If you do not want
+to do it, please contact a project maintainer, and they can help you with it. We do not want this to be a blocker for good code getting contributed.
+
+## 📜 Main Documentation
+
+The content for the main documentation is located in the `/docs` directory of the monorepo.
+
+The documentation is written using a combination of ipython notebooks (`.ipynb` files)
+and markdown (`.mdx` files). The notebooks are converted to markdown
+and then built using [Docusaurus 2](https://docusaurus.io/).
+
+Feel free to make contributions to the main documentation! 🥰
+
+After modifying the documentation:
+
+1. Run the linting and formatting commands (see below) to ensure that the documentation is well-formatted and free of errors.
+2. Optionally build the documentation locally to verify that the changes look good.
+3. Make a pull request with the changes.
+4. You can preview and verify that the changes are what you wanted by clicking the `View deployment` or `Visit Preview` buttons on the pull request `Conversation` page. This will take you to a preview of the documentation changes.
+
+## ⚒️ Linting and Building Documentation Locally
+
+After writing up the documentation, you may want to lint and build the documentation
+locally to ensure that it looks good and is free of errors.
+
+If you're unable to build it locally that's okay as well, as you will be able to
+see a preview of the documentation on the pull request page.
+
+From the **monorepo root**, run the following command to install the dependencies:
+
+```bash
+poetry install --with lint,docs --no-root
+````
+
+### Building
+
+The code that builds the documentation is located in the `/docs` directory of the monorepo.
+
+In the following commands, the prefix `api_` indicates that those are operations for the API Reference.
+
+Before building the documentation, it is always a good idea to clean the build directory:
+
+```bash
+make docs_clean
+make api_docs_clean
+```
+
+Next, you can build the documentation as outlined below:
+
+```bash
+make docs_build
+make api_docs_build
+```
+
+:::tip
+
+The `make api_docs_build` command takes a long time. If you're making cosmetic changes to the API docs and want to see how they look, use:
+
+```bash
+make api_docs_quick_preview
+```
+
+which will just build a small subset of the API reference.
+
+:::
+
+Finally, run the link checker to ensure all links are valid:
+
+```bash
+make docs_linkcheck
+make api_docs_linkcheck
+```
+
+### Linting and Formatting
+
+The Main Documentation is linted from the **monorepo root**. To lint the main documentation, run the following from there:
+
+```bash
+make lint
+```
+
+If you have formatting-related errors, you can fix them automatically with:
+
+```bash
+make format
+```
+
+## ⌨️ In-code Documentation
+
+The in-code documentation is largely autogenerated by [sphinx](https://www.sphinx-doc.org/en/master/) from the code and is hosted by [Read the Docs](https://readthedocs.org/).
+
+For the API reference to be useful, the codebase must be well-documented. This means that all functions, classes, and methods should have a docstring that explains what they do, what the arguments are, and what the return value is. This is a good practice in general, but it is especially important for LangChain because the API reference is the primary resource for developers to understand how to use the codebase.
+
+We generally follow the [Google Python Style Guide](https://google.github.io/styleguide/pyguide.html#38-comments-and-docstrings) for docstrings.
+
+Here is an example of a well-documented function:
+
+```python
+
+def my_function(arg1: int, arg2: str) -> float:
+    """This is a short description of the function. (It should be a single sentence.)
+
+    This is a longer description of the function. It should explain what
+    the function does, what the arguments are, and what the return value is.
+    It should wrap at 88 characters.
+
+    Examples:
+        This is a section for examples of how to use the function.
+
+        .. code-block:: python
+
+            my_function(1, "hello")
+
+    Args:
+        arg1: This is a description of arg1. We do not need to specify the type since
+            it is already specified in the function signature.
+        arg2: This is a description of arg2.
+
+    Returns:
+        This is a description of the return value.
+    """
+    return 3.14
+```
+
+### Linting and Formatting
+
+The in-code documentation is linted from the directories belonging to the packages
+being documented.
+
+For example, if you're working on the `langchain-community` package, you would change
+the working directory to the `langchain-community` directory:
+
+```bash
+cd [root]/libs/langchain-community
+```
+
+Set up a virtual environment for the package if you haven't done so already.
+
+Install the dependencies for the package.
+
+```bash
+poetry install --with lint
+```
+
+Then you can run the following commands to lint and format the in-code documentation:
+
+```bash
+make format
+make lint
+```
+
+## Verify Documentation Changes
+
+After pushing documentation changes to the repository, you can preview and verify that the changes are
+what you wanted by clicking the `View deployment` or `Visit Preview` buttons on the pull request `Conversation` page.
+This will take you to a preview of the documentation changes.
+This preview is created by [Vercel](https://vercel.com/docs/getting-started-with-vercel).

+
+# Documentation Style Guide
+
+As LangChain continues to grow, the surface area of documentation required to cover it continues to grow too.
+This page provides guidelines for anyone writing documentation for LangChain, as well as some of our philosophies around
+organization and structure.
+
+## Philosophy
+
+LangChain's documentation follows the [Diataxis framework](https://diataxis.fr).
+Under this framework, all documentation falls under one of four categories: [Tutorials](/docs/contributing/documentation/style_guide/#tutorials),
+[How-to guides](/docs/contributing/documentation/style_guide/#how-to-guides),
+[References](/docs/contributing/documentation/style_guide/#references), and [Explanations](/docs/contributing/documentation/style_guide/#conceptual-guide).
+
+### Tutorials
+
+Tutorials are lessons that take the reader through a practical activity. Their purpose is to help the user
+gain understanding of concepts and how they interact by showing one way to achieve some goal in a hands-on way. They should **avoid** giving
+multiple permutations of ways to achieve that goal in-depth. Instead, it should guide a new user through a recommended path to accomplishing the tutorial's goal. While the end result of a tutorial does not necessarily need to
+be completely production-ready, it should be useful and practically satisfy the the goal that you clearly stated in the tutorial's introduction. Information on how to address additional scenarios
+belongs in how-to guides.
+
+To quote the Diataxis website:
+
+> A tutorial serves the user’s *acquisition* of skills and knowledge - their study. Its purpose is not to help the user get something done, but to help them learn.
+
+In LangChain, these are often higher level guides that show off end-to-end use cases.
+
+Some examples include:
+
+- [Build a Simple LLM Application with LCEL](/docs/tutorials/llm_chain/)
+- [Build a Retrieval Augmented Generation (RAG) App](/docs/tutorials/rag/)
+
+A good structural rule of thumb is to follow the structure of this [example from Numpy](https://numpy.org/numpy-tutorials/content/tutorial-svd.html).
+  
+Here are some high-level tips on writing a good tutorial:
+
+- Focus on guiding the user to get something done, but keep in mind the end-goal is more to impart principles than to create a perfect production system.
+- Be specific, not abstract and follow one path.
+  - No need to go deeply into alternative approaches, but it’s ok to reference them, ideally with a link to an appropriate how-to guide.
+- Get "a point on the board" as soon as possible - something the user can run that outputs something.
+  - You can iterate and expand afterwards.
+  - Try to frequently checkpoint at given steps where the user can run code and see progress.
+- Focus on results, not technical explanation.
+  - Crosslink heavily to appropriate conceptual/reference pages.
+- The first time you mention a LangChain concept, use its full name (e.g. "LangChain Expression Language (LCEL)"), and link to its conceptual/other documentation page.
+  - It's also helpful to add a prerequisite callout that links to any pages with necessary background information.
+- End with a recap/next steps section summarizing what the tutorial covered and future reading, such as related how-to guides.
+  
+### How-to guides
+
+A how-to guide, as the name implies, demonstrates how to do something discrete and specific.
+It should assume that the user is already familiar with underlying concepts, and is trying to solve an immediate problem, but
+should still give some background or list the scenarios where the information contained within can be relevant.
+They can and should discuss alternatives if one approach may be better than another in certain cases.
+
+To quote the Diataxis website:
+
+> A how-to guide serves the work of the already-competent user, whom you can assume to know what they want to do, and to be able to follow your instructions correctly.
+
+Some examples include:
+
+- [How to: return structured data from a model](/docs/how_to/structured_output/)
+- [How to: write a custom chat model](/docs/how_to/custom_chat_model/)
+
+Here are some high-level tips on writing a good how-to guide:
+
+- Clearly explain what you are guiding the user through at the start.
+- Assume higher intent than a tutorial and show what the user needs to do to get that task done.
+- Assume familiarity of concepts, but explain why suggested actions are helpful.
+  - Crosslink heavily to conceptual/reference pages.
+- Discuss alternatives and responses to real-world tradeoffs that may arise when solving a problem.
+- Use lots of example code.
+  - Prefer full code blocks that the reader can copy and run.
+- End with a recap/next steps section summarizing what the tutorial covered and future reading, such as other related how-to guides.
+
+### Conceptual guide
+
+LangChain's conceptual guide falls under the **Explanation** quadrant of Diataxis. They should cover LangChain terms and concepts
+in a more abstract way than how-to guides or tutorials, and should be geared towards curious users interested in
+gaining a deeper understanding of the framework. Try to avoid excessively large code examples - the goal here is to
+impart perspective to the user rather than to finish a practical project. These guides should cover **why** things work they way they do.
+
+This guide on documentation style is meant to fall under this category.
+
+To quote the Diataxis website:
+
+> The perspective of explanation is higher and wider than that of the other types. It does not take the user’s eye-level view, as in a how-to guide, or a close-up view of the machinery, like reference material. Its scope in each case is a topic - “an area of knowledge”, that somehow has to be bounded in a reasonable, meaningful way.
+
+Some examples include:
+
+- [Retrieval conceptual docs](/docs/concepts/#retrieval)
+- [Chat model conceptual docs](/docs/concepts/#chat-models)
+
+Here are some high-level tips on writing a good conceptual guide:
+
+- Explain design decisions. Why does concept X exist and why was it designed this way?
+- Use analogies and reference other concepts and alternatives
+- Avoid blending in too much reference content
+- You can and should reference content covered in other guides, but make sure to link to them
+
+### References
+
+References contain detailed, low-level information that describes exactly what functionality exists and how to use it.
+In LangChain, this is mainly our API reference pages, which are populated from docstrings within code.
+References pages are generally not read end-to-end, but are consulted as necessary when a user needs to know
+how to use something specific.
+
+To quote the Diataxis website:
+
+> The only purpose of a reference guide is to describe, as succinctly as possible, and in an orderly way. Whereas the content of tutorials and how-to guides are led by needs of the user, reference material is led by the product it describes.
+
+Many of the reference pages in LangChain are automatically generated from code,
+but here are some high-level tips on writing a good docstring:
+
+- Be concise
+- Discuss special cases and deviations from a user's expectations
+- Go into detail on required inputs and outputs
+- Light details on when one might use the feature are fine, but in-depth details belong in other sections.
+
+Each category serves a distinct purpose and requires a specific approach to writing and structuring the content.
+
+## General guidelines
+
+Here are some other guidelines you should think about when writing and organizing documentation.
+
+We generally do not merge new tutorials from outside contributors without an actue need.
+We welcome updates as well as new integration docs, how-tos, and references.
+
+### Avoid duplication
+
+Multiple pages that cover the same material in depth are difficult to maintain and cause confusion. There should
+be only one (very rarely two), canonical pages for a given concept or feature. Instead, you should link to other guides.
+
+### Link to other sections
+
+Because sections of the docs do not exist in a vacuum, it is important to link to other sections as often as possible
+to allow a developer to learn more about an unfamiliar topic inline.
+
+This includes linking to the API references as well as conceptual sections!
+
+### Be concise
+
+In general, take a less-is-more approach. If a section with a good explanation of a concept already exists, you should link to it rather than
+re-explain it, unless the concept you are documenting presents some new wrinkle.
+
+Be concise, including in code samples.
+
+### General style
+
+- Use active voice and present tense whenever possible
+- Use examples and code snippets to illustrate concepts and usage
+- Use appropriate header levels (`#`, `##`, `###`, etc.) to organize the content hierarchically
+- Use fewer cells with more code to make copy/paste easier
+- Use bullet points and numbered lists to break down information into easily digestible chunks
+- Use tables (especially for **Reference** sections) and diagrams often to present information visually
+- Include the table of contents for longer documentation pages to help readers navigate the content, but hide it for shorter pages

+
+When you submit a pull request, there may be additional changes
+necessary before merging it. Oftentimes, it is more efficient for the
+maintainers to make these changes themselves before merging, rather than asking you
+to do so in code review.
+
+By default, most pull requests will have a

+badge in the right-hand sidebar.
+
+If you do not see this badge, you may have this setting off for the fork you are
+pull-requesting from. See [this Github docs page](https://docs.github.com/en/pull-requests/collaborating-with-pull-requests/working-with-forks/allowing-changes-to-a-pull-request-branch-created-from-a-fork)
+for more information.
+
+Notably, Github doesn't allow this setting to be enabled for forks in **organizations** ([issue](https://github.com/orgs/community/discussions/5634)).
+If you are working in an organization, we recommend submitting your PR from a personal

+with the rapid rate of development in this field some may get out of date.
+If you notice this happening, please let us know.
+
+### 💭 GitHub Discussions
+
+We have a [discussions](https://github.com/langchain-ai/langchain/discussions) page where users can ask usage questions, discuss design decisions, and propose new features.
+
+If you are able to help answer questions, please do so! This will allow the maintainers to spend more time focused on development and bug fixing.
+
+### 🙋 Getting Help
+
+Our goal is to have the simplest developer setup possible. Should you experience any difficulty getting setup, please
+contact a maintainer! Not only do we want to help get you unblocked, but we also want to make sure that the process is
+smooth for future contributors.
+
+In a similar vein, we do enforce certain linting, formatting, and documentation standards in the codebase.
+If you are finding these difficult (or even just annoying) to work with, feel free to contact a maintainer for help -
+we do not want these to get in the way of getting good code into the codebase.
+
+### 🌟 Recognition
+
+If your contribution has made its way into a release, we will want to give you credit on Twitter (only if you want though)!
+If you have a Twitter account you would like us to mention, please let us know in the PR or through another means.

+To begin, make sure you have all the dependencies outlined in guide on [Contributing Code](/docs/contributing/code/).
+
+There are a few different places you can contribute integrations for LangChain:
+
+- **Community**: For lighter-weight integrations that are primarily maintained by LangChain and the Open Source Community.
+- **Partner Packages**: For independent packages that are co-maintained by LangChain and a partner.
+
+For the most part, **new integrations should be added to the Community package**. Partner packages require more maintenance as separate packages, so please confirm with the LangChain team before creating a new partner package.
+
+In the following sections, we'll walk through how to contribute to each of these packages from a fake company, `Parrot Link AI`.
+
+## Community package
+
+The `langchain-community` package is in `libs/community` and contains most integrations.
+
+It can be installed with `pip install langchain-community`, and exported members can be imported with code like 
+
+```python
+from langchain_community.chat_models import ChatParrotLink
+from langchain_community.llms import ParrotLinkLLM
+from langchain_community.vectorstores import ParrotLinkVectorStore
+```
+
+The `community` package relies on manually-installed dependent packages, so you will see errors 
+if you try to import a package that is not installed. In our fake example, if you tried to import `ParrotLinkLLM` without installing `parrot-link-sdk`, you will see an `ImportError` telling you to install it when trying to use it.
+
+Let's say we wanted to implement a chat model for Parrot Link AI. We would create a new file in `libs/community/langchain_community/chat_models/parrot_link.py` with the following code:
+
+```python
+from langchain_core.language_models.chat_models import BaseChatModel
+
+class ChatParrotLink(BaseChatModel):
+    """ChatParrotLink chat model.
+
+    Example:
+        .. code-block:: python
+
+            from langchain_community.chat_models import ChatParrotLink
+
+            model = ChatParrotLink()
+    """
+
+    ...
+```
+
+And we would write tests in:
+
+- Unit tests: `libs/community/tests/unit_tests/chat_models/test_parrot_link.py`
+- Integration tests: `libs/community/tests/integration_tests/chat_models/test_parrot_link.py`
+
+And add documentation to:
+
+- `docs/docs/integrations/chat/parrot_link.ipynb`
+
+## Partner package in LangChain repo
+
+:::caution
+Before starting a **partner** package, please confirm your intent with the LangChain team. Partner packages require more maintenance as separate packages, so we will close PRs that add new partner packages without prior discussion. See the above section for how to add a community integration.
+:::
+
+Partner packages can be hosted in the `LangChain` monorepo or in an external repo.
+
+Partner package in the `LangChain` repo is placed in `libs/partners/{partner}` 
+and the package source code is in `libs/partners/{partner}/langchain_{partner}`.
+
+A package is 
+installed by users with `pip install langchain-{partner}`, and the package members 
+can be imported with code like:
+
+```python
+from langchain_{partner} import X
+```
+
+### Set up a new package
+
+To set up a new partner package, use the latest version of the LangChain CLI. You can install or update it with:
+
+```bash
+pip install -U langchain-cli
+```
+
+Let's say you want to create a new partner package working for a company called Parrot Link AI.
+
+Then, run the following command to create a new partner package:
+
+```bash
+cd libs/partners
+langchain-cli integration new
+> Name: parrot-link
+> Name of integration in PascalCase [ParrotLink]: ParrotLink
+```
+
+This will create a new package in `libs/partners/parrot-link` with the following structure:
+
+```
+libs/partners/parrot-link/
+  langchain_parrot_link/ # folder containing your package
+    ...
+  tests/
+    ...
+  docs/ # bootstrapped docs notebooks, must be moved to /docs in monorepo root
+    ...
+  scripts/ # scripts for CI
+    ...
+  LICENSE
+  README.md # fill out with information about your package
+  Makefile # default commands for CI
+  pyproject.toml # package metadata, mostly managed by Poetry
+  poetry.lock # package lockfile, managed by Poetry
+  .gitignore
+```
+
+### Implement your package
+
+First, add any dependencies your package needs, such as your company's SDK:
+
+```bash
+poetry add parrot-link-sdk
+```
+
+If you need separate dependencies for type checking, you can add them to the `typing` group with:
+
+```bash
+poetry add --group typing types-parrot-link-sdk
+```
+
+Then, implement your package in `libs/partners/parrot-link/langchain_parrot_link`.
+
+By default, this will include stubs for a Chat Model, an LLM, and/or a Vector Store. You should delete any of the files you won't use and remove them from `__init__.py`.
+
+### Write Unit and Integration Tests
+
+Some basic tests are presented in the `tests/` directory. You should add more tests to cover your package's functionality.
+
+For information on running and implementing tests, see the [Testing guide](/docs/contributing/testing/).
+
+### Write documentation
+
+Documentation is generated from Jupyter notebooks in the `docs/` directory. You should place the notebooks with examples
+to the relevant `docs/docs/integrations` directory in the monorepo root.
+
+### (If Necessary) Deprecate community integration
+
+Note: this is only necessary if you're migrating an existing community integration into 
+a partner package. If the component you're integrating is net-new to LangChain (i.e. 
+not already in the `community` package), you can skip this step.
+
+Let's pretend we migrated our `ChatParrotLink` chat model from the community package to 
+the partner package. We would need to deprecate the old model in the community package.
+
+We would do that by adding a `@deprecated` decorator to the old model as follows, in
+`libs/community/langchain_community/chat_models/parrot_link.py`.
+
+Before our change, our chat model might look like this:
+
+```python
+class ChatParrotLink(BaseChatModel):
+  ...
+```
+
+After our change, it would look like this:
+
+```python
+from langchain_core._api.deprecation import deprecated
+
+@deprecated(
+    since="0.0.<next community version>", 
+    removal="0.2.0", 
+    alternative_import="langchain_parrot_link.ChatParrotLink"
+)
+class ChatParrotLink(BaseChatModel):
+  ...
+```
+
+You should do this for *each* component that you're migrating to the partner package.
+
+### Additional steps
+
+Contributor steps:
+
+- [ ] Add secret names to manual integrations workflow in `.github/workflows/_integration_test.yml`
+- [ ] Add secrets to release workflow (for pre-release testing) in `.github/workflows/_release.yml`
+
+Maintainer steps (Contributors should **not** do these):
+
+- [ ] set up pypi and test pypi projects
+- [ ] add credential secrets to Github Actions
+- [ ] add package to conda-forge
+
+## Partner package in external repo
+
+Partner packages in external repos must be coordinated between the LangChain team and
+the partner organization to ensure that they are maintained and updated.
+
+If you're interested in creating a partner package in an external repo, please start
+with one in the LangChain repo, and then reach out to the LangChain team to discuss
+how to move it to an external repo.

+# Repository Structure
+
+If you plan on contributing to LangChain code or documentation, it can be useful
+to understand the high level structure of the repository.
+
+LangChain is organized as a [monorepo](https://en.wikipedia.org/wiki/Monorepo) that contains multiple packages.
+You can check out our [installation guide](/docs/how_to/installation/) for more on how they fit together.
+
+Here's the structure visualized as a tree:
+
+```text
+.
+├── cookbook # Tutorials and examples
+├── docs # Contains content for the documentation here: https://python.langchain.com/
+├── libs
+│   ├── langchain
+│   │   ├── langchain
+│   │   ├── tests/unit_tests # Unit tests (present in each package not shown for brevity)
+│   │   ├── tests/integration_tests # Integration tests (present in each package not shown for brevity)

+├── templates # A collection of easily deployable reference architectures for a wide variety of tasks.
+```
+
+The root directory also contains the following files:
+
+* `pyproject.toml`: Dependencies for building docs and linting docs, cookbook.
+* `Makefile`: A file that contains shortcuts for building, linting and docs and cookbook.
+
+There are other files in the root directory level, but their presence should be self-explanatory. Feel free to browse around!
+

+
+# Testing
+
+All of our packages have unit tests and integration tests, and we favor unit tests over integration tests.
+
+Unit tests run on every pull request, so they should be fast and reliable.
+
+Integration tests run once a day, and they require more setup, so they should be reserved for confirming interface points with external services.
+
+## Unit Tests
+
+Unit tests cover modular logic that does not require calls to outside APIs.
+If you add new logic, please add a unit test.
+
+To install dependencies for unit tests:
+
+```bash
+poetry install --with test
+```
+
+To run unit tests:
+
+```bash
+make test
+```
+
+To run unit tests in Docker:
+
+```bash
+make docker_tests
+```
+
+To run a specific test:
+
+```bash
+TEST_FILE=tests/unit_tests/test_imports.py make test
+```
+
+## Integration Tests
+
+Integration tests cover logic that requires making calls to outside APIs (often integration with other services).
+If you add support for a new external API, please add a new integration test.
+
+**Warning:** Almost no tests should be integration tests.
+
+  Tests that require making network connections make it difficult for other
+  developers to test the code.
+
+  Instead favor relying on `responses` library and/or mock.patch to mock
+  requests using small fixtures.
+
+To install dependencies for integration tests:
+
+```bash
+poetry install --with test,test_integration
+```
+
+To run integration tests:
+
+```bash
+make integration_tests
+```
+
+### Prepare
+
+The integration tests use several search engines and databases. The tests
+aim to verify the correct behavior of the engines and databases according to
+their specifications and requirements.
+
+To run some integration tests, such as tests located in
+`tests/integration_tests/vectorstores/`, you will need to install the following
+software:
+
+- Docker
+- Python 3.8.1 or later
+
+Any new dependencies should be added by running:
+
+```bash
+# add package and install it after adding:
+poetry add tiktoken@latest --group "test_integration" && poetry install --with test_integration
+```
+
+Before running any tests, you should start a specific Docker container that has all the
+necessary dependencies installed. For instance, we use the `elasticsearch.yml` container
+for `test_elasticsearch.py`:
+
+```bash
+cd tests/integration_tests/vectorstores/docker-compose
+docker-compose -f elasticsearch.yml up
+```
+
+For environments that requires more involving preparation, look for `*.sh`. For instance,
+`opensearch.sh` builds a required docker image and then launch opensearch.
+
+
+### Prepare environment variables for local testing:
+
+- copy `tests/integration_tests/.env.example` to `tests/integration_tests/.env`
+- set variables in `tests/integration_tests/.env` file, e.g `OPENAI_API_KEY`
+
+Additionally, it's important to note that some integration tests may require certain
+environment variables to be set, such as `OPENAI_API_KEY`. Be sure to set any required
+environment variables before running the tests to ensure they run correctly.
+
+### Recording HTTP interactions with pytest-vcr
+
+Some of the integration tests in this repository involve making HTTP requests to
+external services. To prevent these requests from being made every time the tests are
+run, we use pytest-vcr to record and replay HTTP interactions.
+
+When running tests in a CI/CD pipeline, you may not want to modify the existing
+cassettes. You can use the --vcr-record=none command-line option to disable recording
+new cassettes. Here's an example:
+
+```bash
+pytest --log-cli-level=10 tests/integration_tests/vectorstores/test_pinecone.py --vcr-record=none
+pytest tests/integration_tests/vectorstores/test_elasticsearch.py --vcr-record=none
+
+```
+
+### Run some tests with coverage:
+
+```bash
+pytest tests/integration_tests/vectorstores/test_elasticsearch.py --cov=langchain --cov-report=html
+start "" htmlcov/index.html || open htmlcov/index.html
+
+```
+
+## Coverage
+
+Code coverage (i.e. the amount of code that is covered by unit tests) helps identify areas of the code that are potentially more or less brittle.
+
+Coverage requires the dependencies for integration tests:
+
+```bash
+poetry install --with test_integration
+```
+
+To get a report of current coverage, run the following:
+
+```bash
+make coverage
+```

+# How to load JSON
+
+[JSON (JavaScript Object Notation)](https://en.wikipedia.org/wiki/JSON) is an open standard file format and data interchange format that uses human-readable text to store and transmit data objects consisting of attribute–value pairs and arrays (or other serializable values).
+
+[JSON Lines](https://jsonlines.org/) is a file format where each line is a valid JSON value.
+
+LangChain implements a [JSONLoader](https://python.langchain.com/v0.2/api_reference/community/document_loaders/langchain_community.document_loaders.json_loader.JSONLoader.html) 
+to convert JSON and JSONL data into LangChain [Document](https://python.langchain.com/v0.2/api_reference/core/documents/langchain_core.documents.base.Document.html#langchain_core.documents.base.Document) 
+objects. It uses a specified [jq schema](https://en.wikipedia.org/wiki/Jq_(programming_language)) to parse the JSON files, allowing for the extraction of specific fields into the content 
+and metadata of the LangChain Document.
+
+It uses the `jq` python package. Check out this [manual](https://stedolan.github.io/jq/manual/#Basicfilters) for a detailed documentation of the `jq` syntax.
+
+Here we will demonstrate:

+
+
+### JSON file
+
+```python

+
+### JSON Lines file
+
+If you want to load documents from a JSON Lines file, you pass `json_lines=True`
+and specify `jq_schema` to extract `page_content` from a single JSON object.

+
+## Extracting metadata
+
+Generally, we want to include metadata available in the JSON file into the documents that we create from the content.
+
+The following demonstrates how metadata can be extracted using the `JSONLoader`.
+
+There are some key changes to be noted. In the previous example where we didn't collect the metadata, we managed to directly specify in the schema where the value for the `page_content` can be extracted from.
+
+```
+.messages[].content
+```
+
+In the current example, we have to tell the loader to iterate over the records in the `messages` field. The jq_schema then has to be:
+
+```
+.messages[]
+```
+
+This allows us to pass the records (dict) into the `metadata_func` that has to be implemented. The `metadata_func` is responsible for identifying which pieces of information in the record should be included in the metadata stored in the final `Document` object.
+
+Additionally, we now have to explicitly specify in the loader, via the `content_key` argument, the key from the record where the value for the `page_content` needs to be extracted from.
+
+
+```python
+# Define the metadata extraction function.
+def metadata_func(record: dict, metadata: dict) -> dict:
+
+    metadata["sender_name"] = record.get("sender_name")
+    metadata["timestamp_ms"] = record.get("timestamp_ms")
+
+    return metadata
+
+
+loader = JSONLoader(
+    file_path='./example_data/facebook_chat.json',
+    jq_schema='.messages[]',
+    content_key="content",
+    metadata_func=metadata_func
+)
+
+data = loader.load()
+```
+
+
+```python
+pprint(data)
+```
+
+<CodeOutputBlock lang="python">
+
+```

+```
+
+</CodeOutputBlock>
+
+Now, you will see that the documents contain the metadata associated with the content we extracted.
+
+## The `metadata_func`
+
+As shown above, the `metadata_func` accepts the default metadata generated by the `JSONLoader`. This allows full control to the user with respect to how the metadata is formatted.
+
+For example, the default metadata contains the `source` and the `seq_num` keys. However, it is possible that the JSON data contain these keys as well. The user can then exploit the `metadata_func` to rename the default keys and use the ones from the JSON data.
+
+The example below shows how we can modify the `source` to only contain information of the file source relative to the `langchain` directory.
+
+
+```python
+# Define the metadata extraction function.
+def metadata_func(record: dict, metadata: dict) -> dict:
+
+    metadata["sender_name"] = record.get("sender_name")
+    metadata["timestamp_ms"] = record.get("timestamp_ms")
+
+    if "source" in metadata:
+        source = metadata["source"].split("/")
+        source = source[source.index("langchain"):]
+        metadata["source"] = "/".join(source)
+
+    return metadata

+# How to load Microsoft Office files
+
+The [Microsoft Office](https://www.office.com/) suite of productivity software includes Microsoft Word, Microsoft Excel, Microsoft PowerPoint, Microsoft Outlook, and Microsoft OneNote. It is available for Microsoft Windows and macOS operating systems. It is also available on Android and iOS.
+
+This covers how to load commonly used file formats including `DOCX`, `XLSX` and `PPTX` documents into a LangChain 
+[Document](https://python.langchain.com/v0.2/api_reference/core/documents/langchain_core.documents.base.Document.html#langchain_core.documents.base.Document)
+object that we can use downstream.
+
+
+## Loading DOCX, XLSX, PPTX with AzureAIDocumentIntelligenceLoader
+
+[Azure AI Document Intelligence](https://aka.ms/doc-intelligence) (formerly known as `Azure Form Recognizer`) is machine-learning 
+based service that extracts texts (including handwriting), tables, document structures (e.g., titles, section headings, etc.) and key-value-pairs from
+digital or scanned PDFs, images, Office and HTML files. Document Intelligence supports `PDF`, `JPEG/JPG`, `PNG`, `BMP`, `TIFF`, `HEIF`, `DOCX`, `XLSX`, `PPTX` and `HTML`.
+
+This [current implementation](https://aka.ms/di-langchain) of a loader using `Document Intelligence` can incorporate content page-wise and turn it into LangChain documents. The default output format is markdown, which can be easily chained with `MarkdownHeaderTextSplitter` for semantic document chunking. You can also use `mode="single"` or `mode="page"` to return pure texts in a single page or document split by page.
+
+### Prerequisite
+
+An Azure AI Document Intelligence resource in one of the 3 preview regions: **East US**, **West US2**, **West Europe** - follow [this document](https://learn.microsoft.com/azure/ai-services/document-intelligence/create-document-intelligence-resource?view=doc-intel-4.0.0) to create one if you don't have. You will be passing `<endpoint>` and `<key>` as parameters to the loader.
+
+```python
+%pip install --upgrade --quiet  langchain langchain-community azure-ai-documentintelligence
+
+from langchain_community.document_loaders import AzureAIDocumentIntelligenceLoader
+

+# Text embedding models
+
+:::info
+Head to [Integrations](/docs/integrations/text_embedding/) for documentation on built-in integrations with text embedding model providers.
+:::
+
+The Embeddings class is a class designed for interfacing with text embedding models. There are lots of embedding model providers (OpenAI, Cohere, Hugging Face, etc) - this class is designed to provide a standard interface for all of them.
+
+Embeddings create a vector representation of a piece of text. This is useful because it means we can think about text in the vector space, and do things like semantic search where we look for pieces of text that are most similar in the vector space.
+
+The base Embeddings class in LangChain provides two methods: one for embedding documents and one for embedding a query. The former, `.embed_documents`, takes as input multiple texts, while the latter, `.embed_query`, takes a single text. The reason for having these as two separate methods is that some embedding providers have different embedding methods for documents (to be searched over) vs queries (the search query itself). 
+`.embed_query` will return a list of floats, whereas `.embed_documents` returns a list of lists of floats.
+
+## Get started
+
+### Setup
+
+import Tabs from '@theme/Tabs';
+import TabItem from '@theme/TabItem';
+
+<Tabs>
+  <TabItem value="openai" label="OpenAI" default>
+To start we'll need to install the OpenAI partner package:
+
+```bash
+pip install langchain-openai
+```
+
+Accessing the API requires an API key, which you can get by creating an account and heading [here](https://platform.openai.com/account/api-keys). Once we have a key we'll want to set it as an environment variable by running:
+
+```bash
+export OPENAI_API_KEY="..."
+```
+
+If you'd prefer not to set an environment variable you can pass the key in directly via the `api_key` named parameter when initiating the OpenAI LLM class:
+
+```python
+from langchain_openai import OpenAIEmbeddings
+
+embeddings_model = OpenAIEmbeddings(api_key="...")
+```
+
+Otherwise you can initialize without any params:
+```python
+from langchain_openai import OpenAIEmbeddings
+
+embeddings_model = OpenAIEmbeddings()
+```
+
+  </TabItem>
+  <TabItem value="cohere" label="Cohere">
+
+To start we'll need to install the Cohere SDK package:
+
+```bash
+pip install langchain-cohere
+```
+
+Accessing the API requires an API key, which you can get by creating an account and heading [here](https://dashboard.cohere.com/api-keys). Once we have a key we'll want to set it as an environment variable by running:
+
+```shell
+export COHERE_API_KEY="..."
+```
+
+If you'd prefer not to set an environment variable you can pass the key in directly via the `cohere_api_key` named parameter when initiating the Cohere LLM class:
+
+```python
+from langchain_cohere import CohereEmbeddings
+
+embeddings_model = CohereEmbeddings(cohere_api_key="...", model='embed-english-v3.0')
+```
+
+Otherwise you can initialize simply as shown below:
+```python
+from langchain_cohere import CohereEmbeddings
+
+embeddings_model = CohereEmbeddings(model='embed-english-v3.0')
+```
+Do note that it is mandatory to pass the model parameter while initializing the CohereEmbeddings class.
+
+  </TabItem>
+  <TabItem value="huggingface" label="Hugging Face">
+
+To start we'll need to install the Hugging Face partner package:
+
+```bash
+pip install langchain-huggingface
+```
+
+You can then load any [Sentence Transformers model](https://huggingface.co/models?library=sentence-transformers) from the Hugging Face Hub.
+
+```python
+from langchain_huggingface import HuggingFaceEmbeddings
+
+embeddings_model = HuggingFaceEmbeddings(model_name="sentence-transformers/all-mpnet-base-v2")
+```
+
+You can also leave the `model_name` blank to use the default [sentence-transformers/all-mpnet-base-v2](https://huggingface.co/sentence-transformers/all-mpnet-base-v2) model.
+
+```python
+from langchain_huggingface import HuggingFaceEmbeddings
+
+embeddings_model = HuggingFaceEmbeddings()
+```
+
+  </TabItem>
+</Tabs>
+
+### `embed_documents`
+#### Embed list of texts
+
+Use `.embed_documents` to embed a list of strings, recovering a list of embeddings:
+
+```python
+embeddings = embeddings_model.embed_documents(
+    [
+        "Hi there!",
+        "Oh, hello!",
+        "What's your name?",
+        "My friends call me World",
+        "Hello World!"
+    ]
+)
+len(embeddings), len(embeddings[0])
+```
+
+<CodeOutputBlock language="python">
+
+```
+(5, 1536)
+```
+
+</CodeOutputBlock>
+
+### `embed_query`
+#### Embed single query
+Use `.embed_query` to embed a single piece of text (e.g., for the purpose of comparing to other embedded pieces of texts).
+
+```python
+embedded_query = embeddings_model.embed_query("What was the name mentioned in the conversation?")
+embedded_query[:5]
+```

+# How to install LangChain packages
+
+The LangChain ecosystem is split into different packages, which allow you to choose exactly which pieces of
+functionality to install.
+
+## Official release
+
+To install the main LangChain package, run:
+
+import Tabs from '@theme/Tabs';
+import TabItem from '@theme/TabItem';
+import CodeBlock from "@theme/CodeBlock";
+
+<Tabs>
+  <TabItem value="pip" label="Pip" default>
+    <CodeBlock language="bash">pip install langchain</CodeBlock>
+  </TabItem>
+  <TabItem value="conda" label="Conda">
+    <CodeBlock language="bash">conda install langchain -c conda-forge</CodeBlock>
+  </TabItem>
+</Tabs>
+
+While this package acts as a sane starting point to using LangChain,
+much of the value of LangChain comes when integrating it with various model providers, datastores, etc.
+By default, the dependencies needed to do that are NOT installed. You will need to install the dependencies for specific integrations separately.
+We'll show how to do that in the next sections of this guide.
+
+## Ecosystem packages
+
+With the exception of the `langsmith` SDK, all packages in the LangChain ecosystem depend on `langchain-core`, which contains base
+classes and abstractions that other packages use. The dependency graph below shows how the difference packages are related.
+A directed arrow indicates that the source package depends on the target package:
+
+![](/img/ecosystem_packages.png)
+
+When installing a package, you do not need to explicitly install that package's explicit dependencies (such as `langchain-core`).
+However, you may choose to if you are using a feature only available in a certain version of that dependency.
+If you do, you should make sure that the installed or pinned version is compatible with any other integration packages you use.
+
+### From source
+
+If you want to install from source, you can do so by cloning the repo and be sure that the directory is `PATH/TO/REPO/langchain/libs/langchain` running:
+
+```bash
+pip install -e .
+```
+
+### LangChain core
+The `langchain-core` package contains base abstractions that the rest of the LangChain ecosystem uses, along with the LangChain Expression Language. It is automatically installed by `langchain`, but can also be used separately. Install with:
+
+```bash
+pip install langchain-core
+```
+
+### LangChain community
+The `langchain-community` package contains third-party integrations. Install with:
+
+```bash
+pip install langchain-community
+```
+
+### LangChain experimental
+The `langchain-experimental` package holds experimental LangChain code, intended for research and experimental uses.
+Install with:
+
+```bash
+pip install langchain-experimental
+```
+
+### LangGraph
+`langgraph` is a library for building stateful, multi-actor applications with LLMs. It integrates smoothly with LangChain, but can be used without it.
+Install with:
+
+```bash
+pip install langgraph
+```
+
+### LangServe
+LangServe helps developers deploy LangChain runnables and chains as a REST API.
+LangServe is automatically installed by LangChain CLI.
+If not using LangChain CLI, install with:
+
+```bash
+pip install "langserve[all]"
+```
+for both client and server dependencies. Or `pip install "langserve[client]"` for client code, and `pip install "langserve[server]"` for server code.
+
+## LangChain CLI
+The LangChain CLI is useful for working with LangChain templates and other LangServe projects.
+Install with:
+
+```bash
+pip install langchain-cli
+```
+
+### LangSmith SDK
+The LangSmith SDK is automatically installed by LangChain. However, it does not depend on
+`langchain-core`, and can be installed and used independently if desired.
+If you are not using LangChain, you can install it with:
+
+```bash
+pip install langsmith
+```

+
+Toolkits are collections of tools that are designed to be used together for specific tasks. They have convenient loading methods.
+
+All Toolkits expose a `get_tools` method which returns a list of tools.
+You can therefore do:

+# Initialize a toolkit
+toolkit = ExampleTookit(...)
+
+# Get list of tools

+# How to create and query vector stores
+
+:::info
+Head to [Integrations](/docs/integrations/vectorstores/) for documentation on built-in integrations with 3rd-party vector stores.
+:::
+
+One of the most common ways to store and search over unstructured data is to embed it and store the resulting embedding
+vectors, and then at query time to embed the unstructured query and retrieve the embedding vectors that are
+'most similar' to the embedded query. A vector store takes care of storing embedded data and performing vector search
+for you.
+
+## Get started
+
+This guide showcases basic functionality related to vector stores. A key part of working with vector stores is creating the vector to put in them,
+which is usually created via embeddings. Therefore, it is recommended that you familiarize yourself with the [text embedding model interfaces](/docs/how_to/embed_text) before diving into this.
+
+Before using the vectorstore at all, we need to load some data and initialize an embedding model.
+
+We want to use OpenAIEmbeddings so we have to get the OpenAI API Key.
+
+```python
+import os
+import getpass
+
+os.environ['OPENAI_API_KEY'] = getpass.getpass('OpenAI API Key:')
+```
+
+```python
+from langchain_community.document_loaders import TextLoader
+from langchain_openai import OpenAIEmbeddings
+from langchain_text_splitters import CharacterTextSplitter
+
+# Load the document, split it into chunks, embed each chunk and load it into the vector store.
+raw_documents = TextLoader('state_of_the_union.txt').load()
+text_splitter = CharacterTextSplitter(chunk_size=1000, chunk_overlap=0)
+documents = text_splitter.split_documents(raw_documents)
+```
+
+import Tabs from '@theme/Tabs';
+import TabItem from '@theme/TabItem';
+
+There are many great vector store options, here are a few that are free, open-source, and run entirely on your local machine. Review all integrations for many great hosted offerings.
+
+
+<Tabs>
+  <TabItem value="chroma" label="Chroma" default>
+
+This walkthrough uses the `chroma` vector database, which runs on your local machine as a library.
+
+```bash
+pip install langchain-chroma
+```
+
+```python
+from langchain_chroma import Chroma
+
+db = Chroma.from_documents(documents, OpenAIEmbeddings())
+```
+
+  </TabItem>
+  <TabItem value="faiss" label="FAISS">
+
+This walkthrough uses the `FAISS` vector database, which makes use of the Facebook AI Similarity Search (FAISS) library.
+
+```bash
+pip install faiss-cpu
+```
+
+```python
+from langchain_community.vectorstores import FAISS
+
+db = FAISS.from_documents(documents, OpenAIEmbeddings())

+from langchain_community.vectorstores import LanceDB
+
+import lancedb
+
+db = lancedb.connect("/tmp/lancedb")
+table = db.create_table(
+    "my_table",
+    data=[
+        {
+            "vector": embeddings.embed_query("Hello World"),
+            "text": "Hello World",
+            "id": "1",
+        }
+    ],
+    mode="overwrite",
+)
+db = LanceDB.from_documents(documents, OpenAIEmbeddings())
+```
+
+  </TabItem>
+</Tabs>
+
+
+## Similarity search
+
+All vectorstores expose a `similarity_search` method.
+This will take incoming documents, create an embedding of them, and then find all documents with the most similar embedding.
+
+```python
+query = "What did the president say about Ketanji Brown Jackson"
+docs = db.similarity_search(query)
+print(docs[0].page_content)
+```
+
+<CodeOutputBlock lang="python">
+
+```
+    Tonight. I call on the Senate to: Pass the Freedom to Vote Act. Pass the John Lewis Voting Rights Act. And while you’re at it, pass the Disclose Act so Americans can know who is funding our elections.
+
+    Tonight, I’d like to honor someone who has dedicated his life to serve this country: Justice Stephen Breyer—an Army veteran, Constitutional scholar, and retiring Justice of the United States Supreme Court. Justice Breyer, thank you for your service.
+
+    One of the most serious constitutional responsibilities a President has is nominating someone to serve on the United States Supreme Court.
+
+    And I did that 4 days ago, when I nominated Circuit Court of Appeals Judge Ketanji Brown Jackson. One of our nation’s top legal minds, who will continue Justice Breyer’s legacy of excellence.
+```
+
+</CodeOutputBlock>
+
+### Similarity search by vector
+
+It is also possible to do a search for documents similar to a given embedding vector using `similarity_search_by_vector` which accepts an embedding vector as a parameter instead of a string.
+
+```python
+embedding_vector = OpenAIEmbeddings().embed_query(query)
+docs = db.similarity_search_by_vector(embedding_vector)
+print(docs[0].page_content)
+```
+
+<CodeOutputBlock lang="python">

+```

+```
+
+</CodeOutputBlock>
+
+## Async Operations
+
+
+Vector stores are usually run as a separate service that requires some IO operations, and therefore they might be called asynchronously. That gives performance benefits as you don't waste time waiting for responses from external services.

+# Layerup Security
+
+The [Layerup Security](https://uselayerup.com) integration allows you to secure your calls to any LangChain LLM, LLM chain or LLM agent. The LLM object wraps around any existing LLM object, allowing for a secure layer between your users and your LLMs.
+
+While the Layerup Security object is designed as an LLM, it is not actually an LLM itself, it simply wraps around an LLM, allowing it to adapt the same functionality as the underlying LLM.
+
+## Setup
+First, you'll need a Layerup Security account from the Layerup [website](https://uselayerup.com).
+
+Next, create a project via the [dashboard](https://dashboard.uselayerup.com), and copy your API key. We recommend putting your API key in your project's environment.

+>[Azure Cosmos DB for NoSQL](https://learn.microsoft.com/en-us/azure/cosmos-db/nosql/vector-search) now offers vector indexing and search in preview.
+This feature is designed to handle high-dimensional vectors, enabling efficient and accurate vector search at any scale. You can now store vectors
+directly in the documents alongside your data. This means that each document in your database can contain not only traditional schema-free data,
+but also high-dimensional vectors as other properties of the documents. This colocation of data and vectors allows for efficient indexing and searching,
+as the vectors are stored in the same logical unit as the data they represent. This simplifies data management, AI application architectures, and the
+efficiency of vector-based operations.
+
+#### Installation and Setup
+
+See [detail configuration instructions](/docs/integrations/vectorstores/azure_cosmos_db_no_sql).
+
+We need to install `azure-cosmos` python package.
+
+```bash
+pip install azure-cosmos
+```
+
+#### Deploy Azure Cosmos DB on Microsoft Azure
+
+Azure Cosmos DB offers a solution for modern apps and intelligent workloads by being very responsive with dynamic and elastic autoscale. It is available
+in every Azure region and can automatically replicate data closer to users. It has SLA guaranteed low-latency and high availability.

+
+>Search is foundational to any app that surfaces text to users, where common scenarios include catalog or document search, online retail apps, or data exploration over proprietary content. When you create a search service, you'll work with the following capabilities:
+>- A search engine for full text search over a search index containing user-owned content
+>- Rich indexing, with lexical analysis and optional AI enrichment for content extraction and transformation
+>- Rich query syntax for text search, fuzzy search, autocomplete, geo-search and more
+>- Programmability through REST APIs and client libraries in Azure SDKs
+>- Azure integration at the data layer, machine learning layer, and AI (AI Services)
